How I got 1000+ users in 16 days with my Japan nostalgia app

Quick backstory: I travel to Japan regularly and the post-trip nostalgia was killing me. Built Gachari (https://gachari.com) for daily cultural escapes from Japan in 30 seconds.

What I focused on that maybe helped:

1. Obsessed over my first 10 users

Actually reached out to each one individually. Asked specific questions: "What did you miss most about Japan?" "What didn't work in the app?" "Why did you come back today?" Instead of building what I thought they wanted, I A/B tested my assumptions. Tried gamification vs simple cultural moments. Tested different content types. Turns out they wanted authentic moments that reminded them of specific places, not points or achievements. The feedback completely changed my direction.

2. Fixed my onboarding by asking the right questions

Asked my early users why they stayed vs why others left immediately. Originally asked for signup immediately, but people didn't understand what they'd get. Changed to let them try 3 draws first to see haikus, sounds, stories and THEN optional signup. Made a real difference in retention.

3. Found my real audience where they actually hang out

Facebook feels dead but the communities still there are genuinely engaged. Spent weeks building karma in Japan travel groups, sharing real moments, helping people plan trips. No self-promotion. When I finally posted about my "missing Japan" problem and how I solved it, focused on the pain, not the product, people who felt the same came naturally. One post took me from 20/30 to 500 users. The next 500 came from word of mouth.

The channel will be different for every project, but the principle stays: find where your people already talk about their problems, become part of that community first, then share your story when it's relevant.

4. Ignored feature requests until people actually cared

By "feature requests" I mean my own. You often think your product doesn't work because it's not good enough. WRONG. It doesn't work because nobody cares about it yet. Before this, I was building random stuff nobody asked for thinking more features = more users. Now they're actually asking for notifications, drop rates, referrals. That's when you know you have something worth improving.

Funny thing is, this is when I should START building them, not before, but obviously I lost many days before understanding this.

What didn't work:

Most fancy growth tactics. The authentic "I miss Japan" story performed way better than any marketing copy I tried.

That's about it. Not sure if this helps anyone but figured I'd share since this community has been helpful.

Now actively trying to grow on X if anyone's interested in following along. Might abandon in 2 weeks but will probably learn something shareable along the way. (https://x.com/BenFernBuild)
